Description
The HCMS-29xx series are high
performance, easy to use dot
matrix displays driven by on-board
CMOS ICs. Each display can be
directly interfaced with a
microprocessor, thus eliminating
the need for cumbersome interface
components. The serial IC
interface allows higher character
count information displays with a
minimum of data lines. A variety of
colors, font heights, and character
counts gives designers a wide
range of product choices for their
specific applications and the easy
to read 5 x 7 pixel format allows
the display of uppercase, lower
case, Katakana, and custom user-
defined characters. These displays
are stackable in the x- and y-
directions, making them ideal for
high character count displays.

Notes:
1. In SLEEP mode, the internal oscillator and reference current for LED drivers are off.
2. Average peak pixel current is measured at the maximum drive current set by Control Register 0. Individual pixels may exceed this
value.
3. For the Oscillator Output, Iol = 40 µA.
